FRANCIS J. CROWLEY, OF GLOUCESTER CITY, NEW JERSEY.

MACHINE FOR DRYING CALICO.

SPECIFICATION forming part of Letters Patent No. 266,104, dated October 17, 1882.

Application tiled November 15, 1881. (N o model.)

To all whom z't'mag/ concern Be it known that I, FRANCIS J AMES CRow- LEY, of Gloucester City, in the county of Camden and State of New Jersey, have invented a new and Improved'Machinet'or Drying Calico; and I do hereby declare that the following is a full, clear, and exact description or" the saine.

.My invention relates to a novel construction and combination of parts, as hereinafter described,for preventingescape of steam through thejoints ofthe concentric drying-cylinders, and for facilitating the removal of the calico from the outer cylinder, when required, as hereinafter described.

I will now proceed to describe the construction and arrangement of parts whereby I attain these results, reference being had to accompanying drawings, in which- Figure l is a side elevation, showing acomplete view of one end of a drying-cylinder and portions ot' others that are geared with it, also a part of the frame-work ot' the apparatus. Fig. 2 is a longitudinal section of my im proved cylinder. Figs. '3 and 4 are plan views of one end ofsuch cylinder and connectedparts, showing the two different positions ot1 the gearing. Fig. 5 is a detail enlarged section of a portion of one ot' the cylinders, showing, however, a

slightly-modified construction and arrangement.

I employ a series of hollow drying-cylinders, A B, preferably four in number, as shown in Fig. 1, and each is provided with a gear, C, through which the required rotation is irnparted from the pinion D on counter-shaft E. The body of each cylinder is formed of two hollow concentric cylinders, the inner one, A, being stationary and the outer or inclosing one, B, being adapted to rotate around it. The solid heads of the inner stationary cylinder, A, are supported in a frame, F, and the revolving part B has its bearings on the peripheries of such heads or ends of said inner cylinderthat is to say, the outer cylinder, B, has annular rims a, on whose inner sides are formed circumferential ribs, that t in grooves in the rims b of cylinder A. Steam is conducted through pipe F' and discharged from radial branch pipes d into the annular space between the cylinders A B, and to pack the joint, and thereby prevent escape of steam, a cotton-roll,

Gr, is applied in an annular cavity on the outer side, as shown in Figs. 2 and 5. This roll is held tightly in place by an annular metal plate, H, Fig. 5, that is secured by suitable clampingplates. The right-hand head of' the stationary cylinder A has an annular iiange, e, cast solidwith it, the same being ot'about halt' the diameter ot' the cylinder. On this iiange are placed a loose gear-wheel, C, a movable crown-wheel, I, and stationary crownwheel I. The movable crown-wheel I is placed between the gear C and wheel I. The teeth of the respective wheels I I are truncated and abut each other, by which the gear C is held in close contact -with the rim ofthe revolving cylinder B, and is locked thereto by lateral pins f, so that both B and C normally' revolve together. The movable crown-wheel I is locked to cylinder A by a pivoted catch or pawl, h, which engages with a laterally-projecting handle, g, that serves to move said wheel circumferen: tially7 on the flange e. It will be noted that the teeth otl the respective crown-wheels are straight on one side and inclined on the other, so that they will either interlock or slide on each other, according to the direction in which the wheel I is moved circumferentially.

The operation is as follows The inner cylinder, A, and crown-wheels I I do not revolve, but the gear C and outer cylinder revolve together when locked by pinsf. By detach'ing the pawl h and shifting the wheel I circumferentially by means ot' handle g its teeth may enter the interdental spaces ot' the wheel I',

which permits lateral adjustment of the gear v C, so that its pinsfare withdrawn from the cylinder B and the latter left free to be rotated independently. These parts may be restored to the former position by pulling on the handle g in the reverse direction, whereby the inclined sides of the teeth of the crown-wheels will slide on each other andthe movable wheel I be forced inward, which in turn crowds the gear C inward and into reengagement with the cylinder B. The objectot' therelease of the outer cylinder, B, from gear C, as described, is to allow the cloth to be conveniently unwound or drawn oftfrom it-an operation which not unfrequently becomes necessary, owing to IOO the cloth breaking or becoming lapped around the cylinder.

What I claim as new is- 1. The combination of the roll of elastic packing and annular plate pressing thereon with the xcd and revolving cylinders having 5 ajoint, as specified.

2. The combination, with the fixed and revolving,r cylinder, of the movable wheel I and xcd wheel I, having teeth adapted to mesh or interlock, as specified, the gear provided with lockingpins and mounted loose on the 1o annular ange of thc fixed cylinder, as shown and described, for the purpose specified.
